It's fine at start up. After driving about 20 minutes, I'll come to a light, put in the clutch and the RPMs are somewhere between 1500 and 3000. It picks an idle and sticks there (for example at one light it might be at 2000, next light is 2500, next is 1500. It doesn't actively fluctuate). With the new IAC, sometimes it will return back to normal. I thought it might be the TPS, but doesn't that make the idle fluctuate while seeking it? Sometimes the idle doesn't stick at all. It drives just fine, accelerates fine. The check engine light has never come on. Any ideas?
